To all whom it may concern:

Be it known that we, HENRY J. Grossi?. and VILLIAM VAGNER, both citizensof the United States, residing at Reno, in the county of Washoe andState of Nevada, have invented new and useful Improvements in FlushingApparatus, of which the following is a specification.

This invention relates to flushing appa ratus, and particularly pertainsto flushing tanks used in connection with toilets and the like.

It is the object of this invention to provide a simple, practicalliushing apparatus, so constructed as not to be liable to get out oforder; which is adapted to be connected to a toilet or other fixture inclose proximity thereto, and to be discharged under pressure direct fromthe main source of water supply; and which is exceedingly simple inconstruction, and positive, eficient and silent in operation.

The invention consists of the parts and the construction and combinationof parts as hereinafter more fully described and claimed, havingreference to the accompanying drawings, in which- Figure 1 is a view invertical section of the invention. Fig. 2 is an enlarged detail of thevalves and operating mechanism in their normal position. Fig. 3 is adetail showing the valves in the open or iushing position.

In the drawings, A is a sealed pressure tank or reservoir of anysuitable size, shape or material, in which the operating parts of theinvention are mounted. Suitably secured to the under side of this tankis the discharge pipe 2 which may be attached at its opposite end to anydesired fixture, as a bowl or the like, not necessary here to be shown.Suitably mounted within the head of the pipe 2 at a point adjacent tothe tank cylinder A, is a crank-arm or trigger 3 attached to a shaft 4and adapted to be raised to press against the head of a plunger 5 bymeans of a hand-lever 6. The plunger 5 slides between guides formed on aspider 7 on the hollow flushing valve 8, which latter normally rests onthe seat 9 formed by the upwardly projecting mouth of the discharge pipe2 within tank A. A suitable cushion or buffer washer 10 is held inposition on the seating face of valve 8 by means of a lock nut 11threaded on the outside of the valve. A stern 12 connected to theplunger 5 extends up through valve 8 and is enlarged, at 13, to form aguide which is longitudinally slotted at 14. This stem 12 13,carries atits upper end a pressure releasing valve 15 which seats, at 16, upon thevalve head 8 and is lifted slightly by the action of the trigger 3 inadvance of the opening of the larger valve 8.

A guide stem 17, notched at 18, is secured to an upwardly projectingportion 19 of the pressure releasing valve 15 and slides in a bearing20` formed in the bottom of an inner fiusheregulating tank 21. Thebearing 2O and tank 21 are threaded to a valve cage 22 and form the topthereof. The valve cage 22 is threaded to the upwardly projecting seatportion 9 of the pipe 2, and bears against the bottom of the tank A.Openings 23 are provided in the valve cas ing 22 to allow the water toow freely from the tank A to the discharge pipe 2 when the valve 8 isopened. The tank 21 is open on top and has a perforated bottom, asshown, but these perforations are of limited size so that dischargetherethrough takes place slowly, for the purpose shortly to bedescribed.

A float 24 is pivotally mounted on the long arm of a bell crank lever 25pivoted at 26 to a bearing 27 formed on the bearing 20 with theflush-regulating tank 21. The short arm of the crank lever 25 is pivotedto a sliding bar or latch 28 which is adapted to enter a slot in thebearin 2O and engage the notch 18 in the stem 17 and hold up the valve 8whenever the latter is lifted by the operating lever 6; assuming, ofcourse, the water in the tanks A and 21 is high enough to buoy up theoat 24. This float, in fact, acts with a yielding pressure normally topress the latch 28 against the stem 17 as long as the Water remains at asufficient level in tanks A and 21.

In operation, water from any suitable source of supply, as the citymains, under pressure, is admitted to the flushing tank A at 29, inFig. 1. The water practically fills the tank A and compresses such airas may be therein, up into the upper dome portion 30 of the tank A,which latter we prefer to construct in cylindrical form, as shown inFig. 1. When the tank A is filled, the valves before described and thefloating ball 24 are submerged. The tendency of the ball 24 to rise inthe water causes an upward pull on V the lever-arm 25, and thus keepsthe sliding contact with Vthe notched stemV 17. The filling of the tankA of course fills the flush-regulating Vtank 21 and submerges thefloat2l1.V When through the grooves 14 in the piston 13 to relieve theypressure of water in the tank A,

Y andto a degree equalize the pressure on the two sides of valve A8.Continued pressure by the trigger 3 carries theplunger 5 against theguides 7 and lifts the valve 8 off the seat 9,V thereby allowing therapid'discharge 'of a Vheavy volume o f Y water under pressure fromthetank A into the flushing pipe 2 in the vdirection of the arrows shownin Fig. 3.

Y l The discharge'from tank A throughV open- VVings 23V and around theinsideV tank' 21 is much more rapid than is the discharge from tank21through lthe holes 31 in the bottomV A 0f tank 21.

The upward movement of the stem 17 which is simultaneous with that ofthe valve 8, bringsV the notch 18 above the slidingflatch' 28, whichlatter is caused 'to engage the notch 18 by reason ofthe upward pull ofthe ball 24. The handle 6 may then Ybe released, whereupon the crankarm,3 falls back toits normal position. 'Ihe sliding latch 28 retains thevalve 8 open until' the water in the tank A is discharged, and as tank21' gradually lempties through the "l holes 31 theiioat 2 4 drops untilthe latch 28 is withdrawn from thei notch 18 in the stem 17, whereuponvalves 8 and 15 drop back to theirV closed 'and-*normal position, and`the,

tank A is again l'rapidly refilled through 'the L. pipe 29.Thisarrangement of'a perforated Y inner tankand cushioned valves gives a.45.

flushing apparatus that is almost silent in operation, and one Vin whicha predetermined quantity of water will be discharged 'each f ,i time.
